Cannot seem to remove highlights from text

Just wanted to put this out there for another option (because I couldn't use the other methods listed):

Edit pdf tool-->select text box-->cut the text box-->the highlighting should still remain, then delete it-->paste the text back in.  Can get tricky pasting the text back in because sometimes it doesn't want to paste back into the same exact spot.  Keep trying different locations to paste it in.

I tried removing highlights in Edit mode and it simply didn't work. So frustrating!

How can this be so difficult, yet such an easy solution exists?

1. Open the text for editing.

2. left click on the text box in which the colored marking is present

3. move the text box (I used the down arrow and counted 5 clicks)

4. right click on the colored box, which will not have moved and then click on "delete".

5. move your text box back to its´ correct position (opposite of 3. above).

There are Action Wizard tasks for deleting highlights from PDFs.  If you go into Action Wizard, make a New Action.  Go to more tools and then select 'Execute JavaScripts' and click the plus sign.  Then on the right side click 'Specify Settings' and paste the code below into the box.  Uncheck the 'Prompt User' setting.  Click save and give the command a name like "Delete All Comments", and click save once more.  Then run the command from the 'Actions List'.  You will be prompted to proceed as this action cannot be undone.  

/*Delete All Comments, Annotations, and Markups */

if( app.alert({
cMsg: "Are you REALLY, sure you want to remove all annotations, comments, and markups from this PDF?\n\nClicking 'OK' will remove all annotation, comments, and markups and save (overwrite) the existing file.  If you want to save the comments in this file, click 'Cancel' and save your changes under a different file name.\n\n\tThis action cannot be undone.", // 2nd message to display
cTitle: "DELETE ALL ANNOTATIONS", // title for pop-up box
nIcon: 2, // question icon
nType: 2 // yes/no buttons
}) == 4) {

this.syncAnnotScan();
var tObj = app.thermometer;
var annots = this.getAnnots();
tObj.duration = annots.length;
tObj.begin();



//DELETE ANNOTATIONS////////////////////////////
if (annots!=null){


for (var i=annots.length-1; i>=0; i--) {

tObj.value=i;
tObj.text ="Remaining comments: " + i + " of " + annots.length;
annots[i].destroy();


}
tObj.text = ""
tObj.end();
}

}

EASY WAY - Click on the Highlight tool to select it.  Right click on the Color, change it to WHITE then select to highlighted text you don't want highlighted. It removes the highlight. SAVE the document, then change the highlight back to the color you want.

I have been able to undo highlighting after saving a document. 

1. Go into Edit PDF

2. Select the text you wish to unhighlight.

3. Right click and choose properties.

4. Left click on the coloured square, which will appear as the highlight colour (in my case yellow).

5. Select white as the colour. This will revert to normal text (it does not whitewash it as I thought it might).

There was no need to revert to default, or anything else in this method.

After a lot of tries, here is the easiest way I found to delete highlighting from text:

1. Right click on the highligting.  If the you do not see "Delete" as one of the options, select "Properties".

2. In the bottom left corner of the "Highlight Properties" popup UNCHECK the "Locked" checkbox.

3. Then CHECK the "Make Properties Default" checkbox. Select "OK"

Now right click on the highlighting.  You should now see "Delete" as one of the options.  Also, if you left click on the highlighting, you will see the Trashcan icon.  Clicking either Delete or the Trashcan should delete the highlighting, 

The files were flattened and the highlights were therefore converted from comments to static contents. That will make it much more difficult to remove them. You can do so using the Edit Text & Images tool, or the Redaction tool, but you'll need to do it one at a time.
